摘要：The modern transportation system is increasingly developed during recent *** is an effective solution to set the noise barriers to reduce the traffic noise pollution caused by different kinds of transportation *** deficiencies on co.crete noise barriers and metal noise barriers with rivet structure can be eliminated by a new kind of noise barrier with no-riveted *** mechanical performance examination and aco.stic performance test are co.ducted on the new-designed noise barrier with no-riveted *** results indicate that the maximum stress is 1.74 MPa and the maximum deformation is 1.04 mm with load acting on the unit *** noise reduction co.fficient of this kind of no-riveted noise barrier unit plate is 0.75 and its noise insulation is 40 dB,which were co.form to or superior to the standard ***,this new designed noise barrier meets the field application requirements of mechanical and aco.stic performance,which demonstrates the noise barriers can be widely promoted.
